Survey of changes in ovarian and uterine artery blood flow and indexes by transvaginal Doppler sonography in POI patients and effect of acupuncture on their fertility

Background: Primary ovarian insufficiency (POI) is a common cause of infertility and usually defined by the triad of amenorrhea, estrogen deficiency, and elevated luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in women < 40 years of age. The aim of the present study was to investigate the relationship between uterine and ovarian blood flow with acupuncture and fertility ratio in patients of the Firoozgar Hospital Infertility Clinic. Methods: Twenty-nine patients with POI were included in this clinical trial. FSH, LH, estradiol (E2), and anti-Müllerian hormone (AMH) levels were measured. Patients with Turner syndrome were identified and excluded from the study. Selected patients were evaluated using transvaginal color Doppler sonography used to measure ovarian volume, endometrial thickness, flow rates, and uterine and ovarian artery indexes. Patients were treated with acupuncture twice a week for 5 weeks. After the end of treatment, hormonal assays and an ultrasound examination were repeated to check the changes. Results: Indexes of the uterine arteries (Resistance Index, Pulsatility Index) before versus after the intervention were significantly different (P < 0.00) and uterine vascularity increased after treatment in 22 patients (75.8%). LH and FSH hormone levels were significantly decreased after the intervention (P < 0.00), while AMH and E2 levels were significantly increased after treatment (P < 0.00). The post-intervention right ovarian reserve was significantly increased (P = 0.02), whereas there was no significant difference in left ovarian reserve before vs. after treatment (P = 0.39). Spontaneous menstruation was detected after acupuncture in 16 patients. Conclusions: Our study demonstrated changes in vascularity, hormone levels, menopausal symptoms, and menstrual induction in patients after acupuncture intervention.

Subsequent Acupuncture Reverses the Aftereffects of Intermittent Theta-Burst Stimulation

ObjectiveThis study explored whether acupuncture affects the maintenance of long-term potentiation (LTP)-like plasticity induced by transcranial magnetic stimulation (TMS) and the acquisition of motor skills following repetitive sequential visual isometric pinch task (SVIPT) training.MethodsThirty-six participants were recruited. The changes in the aftereffects induced by intermittent theta-burst stimulation (iTBS) and followed acupuncture were tested by the amplitude motor evoked potential (MEP) at pre-and-post-iTBS for 30 min and at acupuncture-in and -off for 30 min. Secondly, the effects of acupuncture on SVIPT movement in inducing error rate and learning skill index were tested.ResultsFollowing one session of iTBS, the MEP amplitude was increased and maintained at a high level for 30 min. The facilitation of MEP was gradually decreased to the baseline level during acupuncture-in and did not return to a high level after needle extraction. The SVIPT-acupuncture group had a lower learning skill index than those in the SVIPT group, indicating that acupuncture intervention after SVIPT training may restrain the acquisition ability of one’s learning skills.ConclusionAcupuncture could reverse the LTP-like plasticity of the contralateral motor cortex induced by iTBS. Subsequent acupuncture may negatively affect the efficacy of the acquisition of learned skills in repetitive exercise training.

Acupuncture Intervention Protocol: Consensus Process for a Pragmatic Randomized Controlled Trial of Acupuncture for Management of Chronic Low Back Pain in Older Adults: An NIH HEAL Initiative Funded Project

Objective The aim of this article is to describe the consensus process used to develop an acupuncture intervention protocol for an NIH-funded pragmatic randomized controlled trial (PRCT) of acupuncture for the management of chronic low back (cLBP) in older adults (BackInAction). Background CLBP is among leading causes of disability worldwide: almost 33% of US adults 65 and older experience LBP. Acupuncture is effective for cLBP but there is no specific data on older adults. The National Institutes for Health (NIH) funded a PRCT of acupuncture needling for this population. An essential trial milestone was development of a consensus intervention protocol. Methods An Acupuncture Advisory Panel (AAP) was formed with nine members: two physician-acupuncturists, six licensed acupuncturists representing diverse work backgrounds, and an acupuncture researcher. We used a modified Delphi process that included provision of acupuncture trial data, survey data describing how each expert treats cLBP, three conference calls, and between-call email discussion. Results Lively and professional discussions led to a consensus intervention protocol for the BackInAction trial that included steps/staging of care, recommendations for parameters of care session length, number of needle insertion sites, insertion depths, needle retention times, recommended types of needles, both local and distal areas of the body to be treated, acupuncture point options, auricular point options, self-care options, and minimum number of sessions considered ideal. Conclusion Using a modified Delphi process, an expert AAP created a consensus intervention protocol for the PRCT of acupuncture needling for cLBP in patients 65 and older.

Acupuncture Treatment Compensated the Altered Functional Connectivity in the Pain Modulation System on Primary Dysmenorrhea: A Pilot Study

BackgroundPrimary dysmenorrhea (PDM) is the most commonly encountered gynecological problem in reproductive-age women. We previously reported altered functional connectivity between periaqueductal gray matter and other pain-related brain regions in women with PDM, indicating a maladaptation in the descending pain modulation system. Clinically, acupuncture has been suggested as an effective treatment of PDM. Previous animal studies revealed that acupuncture on specific acupoint can produced analgesic effect via descending pain modulation system. In the present study, we used resting-state functional magnetic resonance imaging to investigate possible changes in descending pain modulation after acupuncture treatment in women with PDM. MethodsThirty-four right-handed adult women with PDM participated in this randomized, single-blinded, sham-controlled study. Each patient was randomly allocated to an 8-week verum or sham acupuncture intervention on the bilateral acupoint Sanyinjiao (SP6). Resting-state functional magnetic resonance imaging was conducted before, during, and after the intervention session to measure the spontaneous activity in brain. The functional connectivity maps between periaqueductal gray matter and other pain-related brain regions were generated to reveal the status of descending pain modulation systems.ResultsAfter 8 weeks, both groups reported decreased menstrual pain. However, the patterns of functional connectivity changes in descending pain modulation system were different after the verum or sham intervention. The effect of the verum acupuncture intervention may be underpinned by compensatory and/or resilience changes in descending pain modulation systems, whereas that of the sham acupuncture intervention may be underpinned by cognitive reappraisal of painConclusionsThe dissimilar pattern of the FC alterations after the verum and sham acupuncture indicating that different brain mechanisms may be responsible for the menstrual pain relief in verum or sham acupuncture intervention. These results may contribute to the discussion of whether acupuncture treatment induces therapeutic physiological alterations or its benefit is attributable to the placebo effect.

A randomized controlled trial to assess the effectiveness and safety of acupuncture for overactive bladder: a study in Hong Kong population

Background Around 15% of the Hong Kong population was found to suffer from overactive bladder (OAB), but the current available treatments, such as medication, behavioral therapy and physical therapy are unsatisfactory. Previous studies have suggested that acupuncture may have promising effect for OAB, but some limitations on the study design render the evidence questionable. This study aimed to evaluate the effectiveness and safety of acupuncture treatment for patients with OAB in Hong Kong. Methods One hundred patients with OAB were enrolled. The patients were randomized to receive either active acupuncture or sham needle intervention twice a week for 8 consecutive weeks, and had a follow-up consultation 12 weeks after the completion of acupuncture intervention. The primary outcome assessment was the 3-Day Voiding Diary, which records daytime and night-time urinary frequency and symptoms, at the baseline, the end of the 8-week intervention and 12 weeks after acupuncture intervention. Secondary outcomes included Urine NGF level, Incontinence Impact Questionnaire (IIQ-7) and Urogenital Distress Inventory (UDI-6), as well as Overactive Bladder Symptom Score (OABSS). Results After 16 sessions of treatment, when compared with the baseline, both active and sham acupuncture significantly reduced the frequency of urgency urinary incontinence (UUI), daytime and night-time urinary frequency as well as the scores of IIQ-7, UDI-6 and OABSS. Moreover, the treatment effects could last for at least 3 months. However, no significant difference in frequency of UUI and daytime urinary frequency was found between the active and sham acupuncture groups. On the other hand, the night-time urinary frequency decreased more significantly during the treatment and follow-up in the active acupuncture group than in the sham control group after controlling baseline night-time urinary frequency. Urine NGF level could not be detected by ELISA method in our experiments. Conclusion This study suggests a beneficial effect of acupuncture on improving OAB symptoms. Both active and sham acupuncture treatment were able to improve the symptoms of frequency of urgency urinary incontinence, and the daytime and night-time urinary frequency, while only mild adverse effects were found. This project was unable to establish the specific effect of acupuncture for OAB. Trial registration Chinese Clinical Trial Registry, ChiCTR-INR-16010048. Registered on 29 Nov 2016.
